Vigeland, Kari. Cognitive style among rural Norwegian children. Scand. J. Psychol., 1973, 14, 305–309.-Two hundred 10- or 13-year-olds from two communities with different cultural values were given a Rod and Frame, Block Design, Embedded Figures, Draw a Person, and Vocabulary test. The first three, combined for an index on cognitive style, intercorrelated about 0.5 at both age levels. Older children generally scored higher than the younger, as expected, but boys were not superior to girls-with one exception: among the 13-year-olds in one community, the girls scored lower than the boys. It is suggested that cultural factors may inhibit the ordinary development toward a more articulated cognitive style.  相似文献

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.  相似文献

Fine motor skill proficiency is an essential component of numerous daily living activities such as dressing, feeding or playing. Poor fine motor skills can lead to difficulties in academic achievement, increased anxiety and poor self-esteem. Recent findings have shown that children’s gross motor skill proficiency tends to fall below established developmental norms. A question remains: do fine motor skill proficiency levels also fall below developmental norms? The aim of this study was to examine the current level of fine motor skill in Irish children. Children (N = 253) from 2nd, 4th and 6th grades (mean age = 7.12, 9.11 and 11.02 respectively) completed the Fine Motor Composite of the Bruininks Oseretsky Test of Motor Proficiency 2nd Edition (BOT-2). Analysis revealed that only 2nd grade children met the expected level of fine motor skill proficiency. It was also found that despite children’s raw scores improving with age, children’s fine motor skill proficiency was not progressing at the expected rate given by normative data. This leads us to question the role and impact of modern society on fine motor skills development over the past number of decades.  相似文献

To further evaluate the construct validity of Kagan's Matching Familiar Figures Test (MFF), three different scoring methods—the MFF error measure, the MFF latency measure, and Kagan's double median split—were used to compare learning disabled and behavior disordered boys at two age levels with their normal peers on the frequency with which they were designated as impulsive. In the comparison of 7-year-old and 12-year-old learning disabled boys with the normal children, the MFF error measure identified a greater frequency of the learning disabled boys as impulsive at both age levels. No differences occurred between the learning disabled and the normal boys at either age level on the latency measure. Kagan's double median split procedure differentiated only between the older learning disabled and the normal boys. Thus, combining the latency measure with the error measure detracted from the effectiveness of the error measure. None of the MFF scoring procedures differentiated between the behavior disordered and the normal boys at either age level. Although the findings tend to support the results of studies with normal children in indicating that the error measure is more sensitive than the latency measure, the failure of the error measure to designate a greater frequency of the severely behavior disordered boys as being impulsive than are their normal peers raises further questions about the construct validity of the MFF, regardless of the scoring procedure used.  相似文献

To investigate the development of verbal rehearsal strategies and selective attention in learning disabled children, Hagen's Central-Incidental task was administered to younger learning disabled (M CA = 8.68 years) and normal (M CA = 8.62 years) boys in Experiment 1 and to intermediate (M CA = 10.18 years) and older (M CA = 13.48 years) learning disabled boys in Experiment 2. Also, in Experiment 2, an experimentally induced verbal rehearsal condition was included to determine its effects on serial recall and selective attention performance. In Experiment 1, the serial postion curve of the normals revealed both a primacy and a recency effect, whereas that of the learning disabled revealed a recency effect only. In Experiment 2, both the intermediate and the older learning disabled exhibited both primacy and recency effects under both standard and rehearsal conditions. A developmental analysis of central recall for the three learning disabled groups revealed constant age-related increases in overall central recall and in primacy recall. That the normals recalled more central, but not more incidental, information than the learning disabled in Experiment 1 suggests that the learning disabled are deficient in selective attention. Correlational findings suggest that the selective attention of the learning disabled improves with age. The results were interpreted as support for the hypothesis of a developmental lag in the learning disabled population.  相似文献

Motor skill acquisition occurs while practicing (on-line) and when asleep or awake (off-line). However, developmental questions still remain about whether children of various ages benefit similarly or differentially from night- and day-time sleeping. The likely circadian effects (time-of-day) and the possible between-test-interference (order effects) associated with children's off-line motor learning are currently unknown. Therefore, this study examines the contributions of over-night sleeping and mid-day napping to procedural skill learning. One hundred and eight children were instructed to practice a finger sequence task using computer keyboards. After an equivalent 11-h interval in one of the three states (sleep, nap, wakefulness), children performed the same sequence in retention tests and a novel sequence in transfer tests. Changes in the movement time and sequence accuracy were evaluated between ages (6–7, 8–9, 10–11 years) during practice, and from skill training to retrievals across three states. Results suggest that night-time sleeping and day-time napping improved the tapping speed, especially for the 6-year-olds. The circadian factor did not affect off-line motor learning in children. The interference between the two counter-balanced retrieval tests was not found for the off-line motor learning. This research offers possible evidence about the age-related motor learning characteristics in children and a potential means for enhancing developmental motor skills. The dynamics between age, experience, memory formation, and the theoretical implications of motor skill acquisition are discussed.  相似文献

Ekornås, B., Lundervold, A. J., Tjus, T. & Heimann, M. (2010). Anxiety disorders in 8–11‐year‐old children: Motor skill performance and self‐perception of competence. Scandinavian Journal of Psychology, 51, 271–277. This study investigates motor skill performance and self‐perceived competence in children with anxiety disorders compared with children without psychiatric disorders. Motor skills and self‐perception were assessed in 329 children aged 8 to 11 years, from the Bergen Child Study. The Kiddie‐SADS PL diagnostic interview was employed to define a group of children with an anxiety disorder without comorbid diagnosis, and a control group (no diagnosis) matched according to gender, age, and full‐scale IQ. Children in the anxiety disorder group displayed impaired motor skills and poor self‐perceived peer acceptance and physical competence compared with the control group. Two‐thirds of the anxious boys scored on the Motor Assessment Battery for Children (MABC) as having motor problems. The present study demonstrated impaired motor skills in boys with “pure” anxiety disorders. Anxious children also perceived themselves as being less accepted by peers and less competent in physical activities compared with children in the control group.  相似文献

Although many follow-up studies have been performed on preterm infants, little attention has been devoted to prediction of motor skills in the preschool or school years. We studied the relationship of performance on the Bayley Scales of Infant Development at a mean corrected age of 21 months to performance on the McCarthy Scales of Children's Abilities at a mean corrected age of 44.7 months for 43 appropriate-for-gestational-age (AGA) children born at ≤ 32 weeks gestation. Motor scores were stable over time with a significant correlation between the Bayley Psychomotor Developmental Index (PDI) and the McCarthy Motor subscale (r = 0.60; p = 0.0001). Scores of cognitive abilities also showed a significant correlation between the Bayley Mental Developmental Index (MDI) and the McCarthy General Cognitive Index (r = 0.42; p = 0.009). Small-for-gestational-age (SGA), very low-birthweight (≤ 1500 grams) children scored lower on the McCarthy General Cognitive Index (p = 0.01) and on the Motor subscale (p = 0.047) than the AGA children. We concluded that motor performance of AGA children born at ≤ 32 weeks gestation is stable from toddlerhood to preschool age. We suggest that SGA children be excluded from studies of motor performance of prematurely born children.  相似文献

BackgroundLiterature addressing the effects of television exposure on developmental skills of young children less than 36 months of age is scarce. This study explored how much time young children spend viewing television and investigated its effects on cognitive, language, and motor developmental skills.MethodsData were collected from the Pediatric Clinics at University Medical Center in Southern Taiwan. The participants comprised 75 children who were frequently exposed to television and 75 children who were not or infrequently exposed to television between 15 and 35 months old. The age and sex were matched in the two groups. The Bayley Scales of Infant Development-second edition and Peabody Developmental Motor Scales-second edition were used to identify developmental skills. Independent t-tests, χ2 tests, and logistic regression models were conducted.ResultsAmong 75 children who were frequently exposed to television, young children watched a daily average of 67.4 min of television before age 2, which was excessive according to the American Academy of Pediatrics. Viewing television increased the risk of delayed cognitive, language, and motor development in children who were frequently exposed to television. Cognitive, language, and motor delays in young children were significantly associated with how much time they spent viewing television. The type of care providers was critical in determining the television-viewing time of children.ConclusionWe recommend that pediatric practitioners explain the impacts of television exposure to parents and caregivers to ensure cognitive, language, and motor development in young children. Advocacy efforts must address the fact that allowing young children to spend excessive time viewing television can be developmentally detrimental.  相似文献

The aim of this study was to examine the relationship between motor proficiency and academic achievement in 7 years-old children. A mediating model in which the relation between motor proficiency and academic achievement is mediated by cognitive ability was tested. Participants included 152 children from the longitudinal study Jeunes enfants et leurs milieux de vie (Young Children and their Environments). Motor proficiency was evaluated with the Bruininks-Oseretsky Test of Motor Proficiency (BOT2), cognitive ability with the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) and academic achievement with the Wechsler Individual Achievement Test II (WIAT II). Results showed that motor proficiency, cognitive ability and academic achievement were positively correlated with each other. A structural equation modeling analysis revealed that motor proficiency had a positive effect on academic achievement through an indirect path via cognitive ability. These results highlight the fundamental importance of motor skills in children's academic achievement in early school years.  相似文献

Neuroimaging research indicates that human intellectual ability is related to brain structure including the thickness of the cerebral cortex. Most studies indicate that general intelligence is positively associated with cortical thickness in areas of association cortex distributed throughout both brain hemispheres. In this study, we performed a cortical thickness mapping analysis on data from 182 healthy typically developing males and females ages 9 to 24 years to identify correlates of general intelligence (g) scores. To determine if these correlates also mediate associations of specific cognitive abilities with cortical thickness, we regressed specific cognitive test scores on g scores and analyzed the residuals with respect to cortical thickness. The effect of age on the association between cortical thickness and intelligence was examined. We found a widely distributed pattern of positive associations between cortical thickness and g scores, as derived from the first unrotated principal factor of a factor analysis of Wechsler Abbreviated Scale of Intelligence (WASI) subtest scores. After WASI specific cognitive subtest scores were regressed on g factor scores, the residual score variances did not correlate significantly with cortical thickness in the full sample with age covaried. When participants were grouped at the age median, significant positive associations of cortical thickness were obtained in the older group for g-residualized scores on Block Design (a measure of visual-motor integrative processing) while significant negative associations of cortical thickness were observed in the younger group for g-residualized Vocabulary scores. These results regarding correlates of general intelligence are concordant with the existing literature, while the findings from younger versus older subgroups have implications for future research on brain structural correlates of specific cognitive abilities, as well as the cognitive domain specificity of behavioral performance correlates of normative gray matter thinning during adolescence.  相似文献

The purpose of this study was to evaluate the relationship between body mass index and motor competence in Santal children 5–12 years old. A total of 816 Santal children were studied. Children's adiposity status was assessed by body mass index (BMI) for age z-score based on World Health Organization reference data. Motor competence was measured using the Bruininks-Oseretsky Test of Motor Competence (BOT-2). There was no significant difference in mean BMI z-score between Santal boys (0.13 ± 0.07) and girls (?0.14 ± 0.07). Healthy weight (HW) children scored higher (p < .05) in some individual motor subtests (bilateral competence, balance, running speed and agility, upper limb competence, and strength) and in total BOT-2 score (p < .05) compared with scores for underweight (UW) and overweight (OW) children. Nonlinear regression analysis showed that BMI is a significant independent predictor of motor competence (p < .01). Motor competence showed a curvilinear relationship with BMI-z-score, with the lowest point motor scores in strength and upper limb competence (p < .05) for both UW and OW children compared to HW children who scored highest. The results also indicated that gross motor skills, but not fine motor skills, were poorer among children who were UW or OW compared with HW children.  相似文献

To ascertain whether normal and hyperactive learning disabled children differ in their responses to Kagan's Matching Familiar Figures Test (MFF) as a function of a temporal cue, the stopwatch used in the testing situation, 16 learning disabled and 15 normal 8- and 9-year-old boys were compared. A counterbalanced design, in which each child was administered one-half of the test with a stopwatch (standard administration procedure) and the other one-half of the test without a stopwatch (No-Stopwatch procedure), was used. For the normal children, the MFF latency scores in the two conditions were not correlated, indicating that the stopwatch influenced their performance. For the learning disabled children, however, the MFF latency scores in the two conditions were correlated. A significant difference between the two correlation coefficients indicated that the normal and learning disabled children responded in a different manner to the temporal cue. On the MFF error measure, the correlation between the scores obtained in the two conditions of test administration was significant for the normal children, but not for the learning disabled children. A significant difference between these correlation coefficients again indicated differential responding to the temporal cue by the two groups.  相似文献

Based on the stability and level of performance on standard achievement tests in first and second grade (mean age in first grade = 82 months), children with IQ scores in the low-average to high-average range were classified as learning disabled (LD) in mathematics (MD), reading (RD), or both (MD/RD). These children (n = 42), a group of children who showed variable achievement test performance across grades (n = 16), and a control group of academically normal peers (n = 35) were administered a series of experimental and psychometric tasks. The tasks assessed number comprehension and production skills, counting knowledge, arithmetic skills, working memory, the ease of activation of phonetic representations of words and numbers, and spatial abilities. The children with variable achievement test performance did not differ from the academically normal children in any cognitive domain, whereas the children in the LD groups showed specific patterns of cognitive deficit, above and beyond the influence of IQ. Discussion focuses on the similarities and differences across the groups of LD children.  相似文献

Two studies examined the interactive effect of receptive verbal intelligence measured by the Peabody Picture Vocabulary Test and self-regulatory competencies measured in the delay of gratification paradigm on boys’ aggression. Study 1 participants (N = 98) were middle school, low-income boys primarily ethnic minority. Participants for Study 2 (N = 59) were drawn from a treatment camp for boys from low-income neighborhoods with behavioral adjustment problems. In both studies, the interaction between verbal intelligence and self-regulation was significant such that verbal intelligence was associated with lower aggression to a greater extent among boys who had effective self-regulatory skills than among those who had ineffective self-regulatory skills. The implications of these findings for interventions and for a theory of risk factors in aggression are discussed.  相似文献

Language problems are highly prevalent in younger siblings of children with autism spectrum disorder (HR-sibs), yet little is known about early predictors. There is growing evidence that motor and language development are linked and this connection might be mediated by joint attention. Developmental changes in motor abilities change how children interact with objects and people (e.g., by showing), which may influence language development. This association has however not yet been studied in HR-sibs. The interrelationship between motor, joint attention and language skills was explored in younger siblings of typically developing children (LR-sibs, N = 31) and HR-sibs (N = 32). In both groups, motor skills (composite of fine and gross motor skills) at 10 months influenced receptive and expressive language at 36 months directly and indirectly through joint attention at 14 months. Group status moderated this direct and indirect effect with mainly significant effects in HR-sibs. This indicates that lower motor skills can have cascading effects on joint attention and language in HR-sibs. Consequently, assessment of early motor skills in HR-sibs might hold promise for early identification of motor difficulties but can also be indicative of language difficulties later in life, especially when difficulties with joint attention are also present.  相似文献

We investigated whether motor competence in fundamental motor skills influences sports motor skill learning. Motor competence in fundamental motor skills related to the overhead volleyball serve (i.e., throwing and volleying) was evaluated in 38 children (aged 9–10 yrs) and participants were divided into lower and higher motor competence groups. The groups practiced the volleyball serve under random or constant-random conditions during an acquisition phase and then assessed in pre-test, intermediate, and retention tests. A three-way repeated-measures ANOVA showed performance improvement from pre-test to retention test only for high motor competence groups in fundamental motor skills. Initial competence in fundamental motor skills influences sport skills learning and demonstrates a potential proficiency barrier to learning complex-sports motor skills.  相似文献

ObjectivesPhysical exercise has benefits that go beyond health and well-being, namely in cognitive, motor and psychophysiological areas. The discovery of a shared neural network between action observation and execution (Action-Observation Network) led us to hypothesize that watching human motor action might improve cognitive and motor aspects of performance and proneness for exercise.Design/MethodsSixty participants viewed a Motor (M) (n = 30) or a Non-Motor (NM) (n = 30) movie with strong or weak content of motoric features of human action, respectively. Performance in d2 Attention test, Fitts' Motor task, and a Proneness for Exercise Visual Analog Scale was assessed before and after movie visualization, in a cross-sectional study. Psychophysiological measures were recorded throughout the experiment.ResultsOur results demonstrate an increase in proneness for exercise, and greater improvement in attention-related cognitive aspects in the M group. The aforementioned benefits of action observation did not modulate motor performance. A mental effort deployment was associated to the decrease in heart rate variability after visualization of the NM movie. This was not conducive to attention channeling on task performance. Conversely, M movie observation seemed to be associated to a cognitive load release, affording attention deployment for the resolution of the subsequent tasks.ConclusionsIt seems that some benefits associated to physical practice can result from the mere visualization of movies with human motor action content. These are the improvement in attention-related cognitive skills associated to psychophysiological changes that support a disengagement from mental effort. Crucially, the observation of exercise behavior seems to be a key factor for exercise adherence.  相似文献
